Title: Velocity sensing device for aircraft
Inventor: DUMEZ RAOUL HENRI
IPC: B64D43/02
Filed: 1959-01-23
Abstract: 909,090. Automatic steering control systems. SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Jan. 23, 1959 [Jan. 24, 1958], No. 2555/59. Class 38 (4). [Also in Group XX] The velocity of an aircraft is sensed by the movement along its axis of a rotor exposed to the surrounding air, driven at constant speed, and having a plurality of radial blades each of which is pivotable about its length to vary the pitch thereof. In Fig. 3 a shaft 13, rotated at constant speed and projecting from the nose of a vertical-take-off aircraft, drives through gearing 14 a ring 16 which thus rotates about a portion 18 of a fixed cylinder 7. Articulated links 20 transmit the drive to two rotors 5, 5<SP>1</SP> carrying variable-pitch blades 3, 3<SP>1</SP> respectively. Rotors 5, 5<SP>1</SP> are thus rotated in the same direction about bearing rings 6, 6<SP>1</SP> which have spherical surfaces to permit tilt of rotors 5, 5<SP>1</SP> and are free to slide parallel to the axis of shaft 13 on the surface of cylinder 7. Rotors 5, 5<SP>1</SP> are urged to their normal positions by springs 33, 33<SP>1</SP>, 48, 48<SP>1</SP>. The pitch angles of the blades of the two rotors are opposite and the force of air due to movements of the aircraft along its roll axis, i.e. the axis of shaft 13, causes movements of rings 6, 6<SP>1</SP> relative to cylinder 7 and hence coils 35, 35<SP>1</SP> relative to magnetic cores 34, 34<SP>1</SP> so that corresponding electrical signals are produced. The force of air due to movements of the aircraft along the yaw axis, for example, lying in the plane of the paper, causes a torque to be applied to rotor 5 about that axis so that, due to the gyroscopic effect, rotor 5 tilts about ring 6 to move, through rods 47, a spherical housing 28 and hence coils 40, 41 relative to a magnetic core 34 to produce corresponding electrical signals. In a similar manner the force of air due to movements of the aircraft along the pitch axis may cause production of electrical signals in a spherical pick-off 28<SP>1</SP> operated through rods 47<SP>1</SP> from rotor 5<SP>1</SP>. Rotation of the aircraft about the pitch or yaw axis also causes pick-off 28 or 28<SP>1</SP> to produce a corresponding electrical signal owing to the gyroscopic tendency of rotors 5, 5<SP>1</SP> to remain stationary during such a turn. Electrical signals corresponding to various movements of the aircraft may be obtained by suitably combining the outputs of the several pick-offs and used to stabilize the position of the aircraft relative to the surrounding air by control of steering members of the aircraft. The pitch of blades 3, 3<SP>1</SP> is cyclically varied in dependence on rotor position by links 30, 30<SP>1</SP> coupling the blades to ring 16. Rotation of the two sets of blades in opposite directions and retraction of the assembly inside the aircraft when vertical flight is complete is referred to.

Abstract: 1,202,323. Jet propulsion nozzles. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Jan. 17, 1968 [Jan. 18, 1967], No.2636/68. Heading F1J. A jet propulsion nozzle of the kind comprising a primary gas duct 1 opening into a secondary duct defined by a fairing 3 of larger cross-section than the primary duct and extending downstream beyond the exit 2 from the primary duct has a silencer formed by circumferentially spaced flaps 13 pivoted to the fairing so as to be movable into an operative position in which the downstream portions of the flaps penetrate the stream of gas 4 leaving the exit of the primary duct, the flaps in the non-operative position being retracted into a wall of the fairing. The nozzle also includes area varying flaps 10 pivoted about axes 11 at the downstream end of the fairing 3. The flaps 13 may each comprise, Fig. 1a, a plate 17 pivoted about an axis 14 on the fairing 3 by means of two links 16. The turbulance induced by the plates 17 assists mixing of the primary hot gas stream 4 with the surrounding secondary air F to effect silencing. The plates 13 may, alternatively, be of parallelogram shape, Fig. 3 in which case when the plates are swung inwards the edge 21 of each plate reaches the gas stream 4 before the edge 22 causing a swirling motion of the gas and thus improving mixing with the secondary air. Stiffening ribs 23 may be provided on the plates 13. In further modifications, Figs. 2, 4, 5 (not shown), the plates 13 are of rectangular, curved parallelogram or trapezium shape, in the latter case the pivotal axes 14 of the plates being oblique to the nozzle axis. The plates 13 may overlap the flaps 10, recesses 18 being provided in the upstream ends of the flaps 10 to accommodate the overlapping portions of the plates 13 when the latter are in the inoperative position and it is desired to swing the flaps 10 inwards.

Title: Acceleration enrichment circuitry for electronic fuel system
IPC: F02D41/04
Filed: 1972-01-19
Abstract: 1339404 Electronic fuel injection systems for I.C. engines BENDIX CORP 19 Jan 1972 [25 Jan 1971] 2649/72 Heading G1N In an I.C. engine, intermittant, fuel injection system, an acceleration enrichment circuit is provided and includes an analogue circuit which provides an output signal, indicative of the magnitude of and rate of change of a throttle control member setting, to control the duration of injection valve opening pulses in such manner that the duration is initially lengthened and the lengthening is decreased thereafter in a predetermined manner. Additionally, upon a throttle control setting charge of sufficient magnitude and rate, an additional injection valve opening pulse may be triggered. As described, the fuel injection system, Figs.1 and 3 (not shown), includes an injection valve opening pulse generating circuit of the type which provides two consecutive opening pulses, the first being generated by a monostable multi-vibrator in dependence upon engine rotation and intake manifold pressure, and the second being generated upon termination of the first and having a duration dependent upon the duration of the first pulse and engine temperature. The throttle control member is connected to the throttle valve in the intake manifold via a lost-motion device, Fig.2 (not shown), such that fuel enrichment is signalled before the quantity of air to the engine is increased. The setting of the throttle control member varies the position of a slider of a potentiometer which slider is connected to the input A of an amplifier 200. The output of the amplifier is connected to the analogue circuit 202 and to a switching circuit 204. The analogue circuit 202 provides its output at C to control either the duration of the first or second pulse of the opening pulse generating circuit by varying the energization of the intake pressure sensor or the energization of the temperature sensor. The RC constant of the circuit 202 determines the decrease of lengthening of the opening pulses. The switching circuit 204 provides an output at D to a pulse circuit, Fig.5 (not shown), for providing the additional opening pulse.

Abstract: 431,036. Memorandum appliances. BLACK, H. D., 39, St. James's Street, Westminster, and WEBB, C. F., 24, Deane Way, Eastcote, Middlesex. Jan. 28, 1935, No. 2784. Addition to 426,867. [Class 16] [See also Group XIX] In means for rendering the feed-mechanism of a manifold-writing device inoperative, as described in the parent Specification, the means responsive to extraneous pressure on the forms comprise a locking-device to prevent the release of a member, which is manually displaced against the tension of a spring, and serves, when released, to actuate the feed-mechanism. The drums 2, 4, which feed the forms over the writing-platform 3, gear with the toothed periphery of a maltese wheel 7, which is twined through an angle of 60‹ at each operation of a pin-wheel 8. The pin-wheel is operated by trigger mechanism of the form described in Specification 434,601, [Group XIX], and comprising a lever 9, which can be operated against the tension of a spring by a hand lever. The lever 9 carries with it a hook-shaped lever 10 until a nose 11 thereon engages a fixed pin 12, whereupon the lever 10 is released from the lever 9 and is drawn back by a spring. During this movement, the lever 10 engages and rotates the pin wheel 8 and effects the feed. When the writing- platform 3 is depressed, it acts through a pivoted rod 15 and a lever 21 to shift a bar 24, a block 25 on which it rests then prevents the disengagement of the lever 10 from the lever 9, so that the pin-wheel is not actuated. The drums 2, 4 have peripheral grooves to receive projections on the ends of the platform 3, so that the surface of the platform is tangential to the drums, whereby the feeding of the forms is facilitated.

Title: Improvements in or relating to stressing concrete
IPC: E04C5/08
Filed: 1960-01-26
Abstract: In pre-stressed reinforced concrete, the reinforcing rods or wires are coated with a concrete retarder to delay adhesion between the reinforcement and the surrounding concrete.  The reinforcement in preferably post-tensioned, but may be pre-tensioned in which case only the end portions are coated.  The reinforcement may comprise smooth wires or rods but is preferably a cable consisting of spirally wound rods.  The concrete retarder, of which many examples are given, may be applied in a resinous emulsion or dispersion, or an alcohol solution of the retarder and a film-forming agent.  The resinous component is water-insoluble but soluble in alkaline water in the concrete, and also serves to protect against rust.  In a modification the retarder is applied in aqueous solution including a water-soluble thickening agent. Specification 405,508 is referred to.

Abstract: 1403857 Apparatus for stripping moulds from castings GENERAL ELECTRIC CO 19 Jan 1973 [24 Jan 1972] 2881/73 Heading B3F An apparatus for stripping a multipart mould 12 from a cylindrical casting 14 comprises an arbor 16, clamping means 33 movable radially relative to said arbor, said clamping means being able to engage a mould section disposed about said arbor, means for retracting the clamping means 33 from said arbor to apply a force to the engaged section of said mould, means for maintaining stripped mould sections at a radially displaced location relative to the casting 14 in a plane parallel to the plane of the section when on the casting, and means for moving the clamping means 33 towards the arbor to apply force to individual mould sections to reassemble the sections into a cylindrical structure. The mould may be a centrifugal casting mould composed of four arcuate sections 12a having quadrants of annular plates 12b attached thereto. It is lowered over the arbor 16 and supported on a turntable 26 with pins 69 extending from the end of the mould being received in radially extending slots 70. After the bolts holding the mould sections 12a together have been removed, a carriage 43 carrying the clamping means 33 and a support 52 is moved along rails (45) by a piston and cylinder unit 48 until the front end 53 of the support 52 engages the arbor 16. The jaw 33 is then moved forward by a large diameter piston and cylinder unit 42 until it contacts the mould. Pins 41 are then driven through aligned apertures in the jaw 33 and mould brackets 39 to lock the jaw to said brackets. Plates 75 are now expanded radially outward from the arbor 16 to engage the inner periphery of the casting 14 and the jaw 33 retracted by the unit 42 to strip the engaged mould section from the casting . The carriage 43 is then withdrawn until the stripped mould section reaches a desired position on the turntable 26, at which point the pins 41 are moved upwards to free the jaw 33 from the mould section and said section left standing on the turntable supported by its annular plate segment 12b. After a further retraction of the carriage 43, the turntable is rotated to bring another mould section into alignent with the jaw 33 and the process repeated until all the sections have been stripped from the casting. The casting may now be lifted vertically off the arbor 16 and the mould reassembled by pushing its sections back towards the arbor using the jaw 33. Operation of the machine is controlled by limit switches and stepping relays which generate output signals on successive terminals to initiate the various hydraulic drives.

Abstract: 1501752 Hauling G LOSSERANDMADOUX 24 Jan 1975 [24 Jan 1974 8 Nov 1974] 3293/75 Heading B8B A machine for hauling a cable C or other elongate body comprises a drive wheel 3 and an adjustable rotary pressing wheel 4, between which the cable passes for gripping and hauling, the cable being laterally guided by adjustable alignment rollers 8. The drive wheel 3 mounted on a drive shaft 2 comprises two coaxial hubs each carrying a peripheral circular sectioned pneumatic or solid elastic tyre, the two tyres providing a nip therebetween which acts also to laterally guide the cable C. The pressing wheel 4 is also formed with a circular sectioned pneumatic or solid elastic tyre and both the pressing and drive tyres have adhesion increasing surface formations. The pressing wheel 4 is rotatable on an axle 4<SP>1</SP> at the end of an arm 5 pivoted to the machine frame 1 at 1<SP>1</SP>, a toothed sector plate 5<SP>1</SP> being formed rigid with the arm 5. Adjustment of the wheel 4 to vary the pressing force on the cable 5, is effected by a pivoted lever 6 which upon normal upward movement of the free end thereof limited by a stop 1<SP>3</SP>, causes compression of a calibrated spring or block 7 while a pawl on the lever overrides the toothed sector. As soon as the lever is released, the pawl engages the toothed sector 5<SP>1</SP> and the spring or block 7 applies its stored energy to the arm to press the roller 4 on to the table C. The lateral guide rollers 8 are mounted on a pair of arms pivotally mounted in the frame 1 and symmetrically displaceable through a manual linkage arrangement to facilitate cables of various cross-sections. In the embodiment of Fig. 5, the pressing roller 13 having an integral toothed sector plate 13<SP>2</SP>, is manually pivoted about an axis 14 into contact with the cable, whereafter pressure is applied to the cable by the wheel which is further moved by a pawl and lever system 15, 16. The latter comprises a hand lever 16 pivoted at A to the frame 1 and being further pivoted to links 16<SP>3</SP> and 15 through pivots B and D, the link 15 having one end pivoted to the frame at 14 and pivotally carrying a pawl 15<SP>1</SP> part way along its length. With the lever 16 in the position shown, the gravity pivoted pawl 15<SP>1</SP> is in engagement with an adjustable stop 17 on the frame, to hold the pawl out of engagement with the sector 13<SP>2</SP>. Upon moving the end 16<SP>2</SP> of the lever 16 in the direction of arrow F, the link 15 rotates clockwise about the pivot 14 until the pawl 15<SP>1</SP> becomes free of the stop 17 and pivots into engagement with the sector teeth whereafter further movement of the lever 16 also presses the wheel 13 on to the cable C to a limited extent determined by an over centre position of the linkage pivots A, B, D. The lateral guide rollers 19 are mounted on crossed levers for symmetrical adjustment about an axle 21, the adjustment lockable frictionally by a lever 22.
